Metalwork Grid for the Cushman Floor

The dimensions are listed below left and are due to the design of a type of
weldedqueen excluder grid that is manufactured byB.J. Engineering. Who
should be contacted if you wish to purchase the metalwork.

However, tolerances must not accrue in a
cumulative manner. I have assumed that the jig will incorporate pegs or spacer
strips to give consistency. Also any increase on 417 mm for the pack
width must be subtracted equally from the 12 mm protrusion of the
tie rods.The 20 mm height can have a tolerance of
+0.5 mm -0.5 mmand the 16.1 mm section width will vary due to tolerances
on the gaps between the strips however the pitch should be maintained at
19.1 mm+0.3 mm -0.2 mm

The spot weld tabs are shown in the small sketch at right and
are 1.5 mm long.
